Hello, Rosemary, No, it is not kefir; kefir is a very thin, liquidy yogurt. The yogurt we purchase is made by various Armenian outfits locally: Abali brand, Byblos, Karoun and Sadaf are some of the more widely-distributed brands. They also make lebni and kefir, among other ME products. We purchase ours at a Middle Eastern market about 2 blocks from our house. The yogurt is so thick you can stand a knife up in it. Karoun is our favorite brand. To my knowledge, Sadaf is a very widely distributed brand of ME products and has a web site, which may indicate distributors in your area. We love it with a little passion fruit or lime syrup mixed in with our fruit for breakfast. Yogurt also makes a wonderful marinade with garlic, cumin, cayenne and a bit of coriander, for chicken. You will be amazed at how it tenderizes the meat! Happy hunting and good growing to you. Ron
